Cyclopital3D SONYTD300-SBE1 overview

  • 1Description

The Sony TD300 Stereo Base Extender from Cyclopital3D is suitable for maintaining accurate depth portrayal when subjects are more distant from the camera. The camera allows you to zoom (up to a factor of 7x) for adjusting the scale of X and Y and with the SBE, you can also increase the scale in the Z dimension to increase the depth portrayed in the images you capture. It is especially useful for capturing the action in sporting events, getting up close at concerts, or shooting wildlife while maintaining your distance, and practically anytime you want to get a close look at your subject without getting too close to it.

The SBE uses suitably aligned high-quality front surface mirrors to effectively increase the stereo base from 1.7 to 7.0” (45 to 180mm).The lengthening of the stereo base allows you to get 4x further away from your subject while still maintaining an optimal level of parallax. This SBE (Stereo Base Extender) is only needed for subjects farther than about 13.1’ (4m) away from the camera. Your subject should generally be the closest object in the scene. When using the SBE, objects in the foreground closer than 13.1’ (4m) could cause deviation and make the image uncomfortable to view 3D, depending on the background. Furthermore, the SBE also includes 2 custom made lens hoods, which can be easily removed when not needed.

The Sony PMW-TD300 Camcorder allows you to zoom in, increasing the scales of X and Y up to a factor of six (7x zoom). Using the Stereo Base Extender, you can also increase the scale in the Z dimension too. The SBE increases the interaxial (lens spacing) by 4 times from 1.7 to 7.0” (45 to 180mm). The 4x interaxial makes your subjects appear 4 times closer than they actually are; if you also zoom to make them 4 times bigger, then it’s like you have moved your camera to a position 4 times closer.

Using the SBE with lesser values of zoom add depth to the scene, but the expanded scale in Z also makes the world appear somewhat miniaturized (hyper-stereo condition). Zooming in without the base extender will make the world look bigger, but also flatter with less depth, particularly in the subjects themselves. Taken to extreme zooming without increasing the stereo base can cause card-boarding, where the subjects do not show the roundness one sees in the real world; instead subjects may look like they are painted on cardboard cutouts.

Errors in the scale of X and Y (errors in the aspect ratio) of an image are clearly visible with less than a 20% difference in the scale of X vs. Y. Fortunately, the sensitivity to scale errors in the Z dimension is much more forgiving. However, as the error in the scale of Z approaches 200%, artifacts such as miniaturization and card-boarding become more apparent. Having a Z-scale to play with is the advantage of 3D cinematography. The SBE gives you an important and much needed tool to address the creative opportunities of 3D depth and opens up a whole new world of possibilities. Optimal depth portrayal is a major key to achieving good results with 3D film and video, and the Stereo Base Extender further enables professionals to reach their goals.
